SHINGLE Filed July 28, 1956 7 W EH50 I? 71222] f k Nowwq Patented Jan.18, 1938 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to surface covering bodies of the nature ofshingles.

The primary object of the present invention is to provide an improvedshingle of the type which 5 is formed to represent several ordinaryshingles,

in which a novel body design is produced which will efiect closeengagement between two edges of the shingle body and the underlyingsupporting structure when the shingle is secured in place in the usualmanner.

Another object of the invention is to provide an improved strip shinglehaving integral raised reinforcing ribs which in addition tostrengthening the shingle body, serve as a guiding means for placinganother strip in position and also serve to give the illusion of severalshingles of ordinary width lying in side-by-side relation.

A still further object of the invention is to provide a strip shinglehaving integral raised ribs extending part-way across the strip wherebya flat portion is provided against which a superimposed shingle stripmay be secured and having indicating or marking means lying between theribs for assisting in locating a second or superimposed shingle strip inthe proper position.

The invention will be best understood from a consideration of thefollowing detailed description taken in connection with the accompanyingdrawing forming part of this specification, with so the understanding,however, that the invention is not confined to any strict conformitywith the showing of the drawing but may be changed or modified so longas such changes or modifications mark no material departure from thesalient fea- 5 tures of the invention as expressed in the appendedclaim.

In the drawing:

Figure 1 is a view in plan of a shingle strip constructed in accordancewith the present invention showing the same applied over a starterstrip.

Fig. 2 is a view in section taken transversely of two of the shinglestrips and the starter strip and showing one of the shingle strips inthe condition which it assumed before it is secured in place; and

Fig. 3 is a section on the line 3-3 of Fig. 1.

Referring now more particularly to the drawing, the numeral i generallydesignates a strip shingle constructed in accordance with the presentinvention, which shingle is preferably formed of a composition ofasbestos and asphalt in such proportion as to produce a semi-flexiblematerial hard enough to saw but sufliciently yieldable as to enable itto be easily out with heavy cutters such as tin snips. This shingle isof elongated rectangular outline, as illustrated, and is initiallyformed to have a slight transverse bow or curvature whereby when it islaid upon the sheathing of a roof to which it is tobe secured thecentral part will be raised up over the sheathing and a spring-liketension will be obtained to hold the top and bottom edges in firmcontact with the sheathing and thus when the shingle is secured down bythe nail 2, these contacting edges will be drawn more firmly intoengagement with the sheathing than would be the case with an initiallyformed flat shingle, so as to establish a tight wind-proof andwater-proof joint.

Each of the shingle strips is provided with a series oi transverselydirected ribs 3 which extend from the outer or bottom edge of theshingle, as shown. Where the shingles are to be used upon a roof theseribs are preferably of a length equal to three eighths of the width ofthe shingle and when they are to be used as siding shingle's the lengthof the ribs is preferably approximately three sevenths of the width ofthe shingle. The top edge of the shingle is beveled as indicated at 4,through a distance approximating one-fourth of the width of the shingle.The bevel decreases toward the top edge from the full thickness of theshingle to a thickness of approximately three thirty-seconds of an inchor half the shingle thickness.

At the upper or inner ends of the ribs 3, nail depressions 5 are formed.These are in spaced relation. with the adjacent ends of the ribs so thatwhen a single shingle is placed over the first the lower edge of thesecond shingle will completely cover the nails. As indicated the secondshingles are placed with their lower edges in contact with the innerends of the ribs of the underlying shingle so that the resultant efiectis that of a series of shingles of ordinary or standard width laid inthe usual manner, that is, with the edges of one row in staggeredrelation with the edges of the underlying row or they may be in placingthe shingles with the ribs 01' one strip of one shingle strip exactly ona center line between the ribs and theunderlying strip is assured.

The numeral 8 represents the usual starter strip which is placed alongthe edge 01 a roof to have the first row of shingles or shingle stripsdisposed thereover so that the said row will assume the proper angularrelation with the roof sheathing to insure the following rows ofshingles lying flat and form a water-proof joint.

From the foregoing it will be readiLv apparent that a shingle stripconstructed in; accordance with the present invention may be easilyhandled and quickly applied because 01' the fact that the raised ribs orone already applied row of strips provide a guide means for the placingof the next row and-thus prevent the operator from getting the edge ofthe row out 01' alinement with the row of strips which have already beenapplied.

It will also be apparent that by providing shingle strips with themarking points I the strips can be readily placed so that the ribs 0!one row of strips will follow directly upon the center line between theribs or the next row and thus the operator can work rapidly withouttaking the time to measure or otherwise carefully determine the positionin which the strip should be placed.

1 claim:--

A shingle, comprising an elongated flat sheet oi material having anunbroken edge contour throughout and an undersurface which is flat andunbroken throughout, said strip being tapered from a line extendinglongitudinally and inset a substantial distance from one longitudinaledge to the adjacent edge, a plurality of ribs formed upon the topsurface of and integral with the strip and extending from the otherlongitudinal edge transverselyof the strip and terminating short of saidtaper line, and said shingle being slightly bowed transversely, theconcave side being the underside 0! the shingle whereby the shingle whenflattened out by elements securing it to a root surface will have itstapered edge pressed firmly against the underlying surface.
